LinkMeUp. Release 11. Cisco TAC, CEF, FIB
We finish the first year of the podcast on a very positive note - Dmitry Jdima and Cisco TAC engineer Anatoly Tsyganenko are visiting us.
Everything that you would like to know about the work of the technical support center, how cases handle in tsisko, and what analysis tools the engineers have in the first part of the podcast.
Next will be a quality story about the mechanisms of Proccess Switching, Fast Switching and Cisco Express Forwarding. We will dive into the RIB, FIB, the implementation of all this in hardware, see how the package is processed on the linear, processing boards and switching factories.
Pretty hardcore and turned out for the duration and depth.
